Matthew 26:35

Peter understood the Lord to have foretold that he should deny Him under terror of death, and therefore he declares that though death were imminent, nothing could shake him from his faith; and the other Apostles in like manner in the warmth of their zeal, valued not the infliction of death, but human presumption is vain without Divine aid.

But you will ask, whether it were possible that Peter should not have been offended, when once the Saviour had said, All ye shall be offended in me. To which one will answer, what is foretold by Jesus must of necessity come to pass; and another will say, that He who at the prayer of Ninevites turned away the wrath He had denounced by Jonas, might also have averted Peter's offence at his entreaty. But his presumptuous confidence, prompted by zeal indeed but not a cautious zeal, became the cause not only of offence but of a thrice repeated denial. And since He confirmed it with the sanction of an oath, some one will say that it was not possible that he should not have denied Him. For Christ would have spoken falsely when he said, Verily I say unto thee, if Peter's assertion, I will not deny thee, had been true. It seems to me that the other disciples having in view not that which was first said, All ye shall be offended, but that which was said to Peter, Verily I say unto thee, &c. made a like promise with Peter because they were not comprehended in the prophecy of denial. Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples. Here again Peter knows not what he says; he could not die with Him who was to die for all mankind, who were all in sin, and had need of some one to die for them, not that they should die for others.

"But Peter answered and said, Though all men should be offended because of Thee, yet will I never be offended." What sayest thou, O Peter? the prophet said, "The sheep shall be scattered;" Christ hath confirmed the saying, and sayest thou, No? Is not what passed before enough, when Thou saidst, "Far be it from Thee," and thy mouth was stopped? For this then He suffers him to fall, teaching him thereby to believe Christ in all things, and to account His declaration more trustworthy than one's own conscience. And the rest too reaped no small benefit from his denial, having come to know man's weakness, and God's truth. For when He foretells anything, we must no longer be subtle, nor lift up ourselves above the common sort. For, "thy rejoicing," it is said, "thou shall have in thyself, and not in another." For where he should have prayed, and have said, Help us, that we be not cut off, he is confident in himself, and saith, "Though all men should be offended in Thee, yet will I never;" though all should undergo this, I shall not undergo it, which led him on by little and little to self-confidence. Christ then, out of a desire to put down this, permitted his denial. For since he neither submitted to Him nor the prophet (and yet for this intent He brought in the prophet besides, that they may not gainsay), but nevertheless since he submitted not to His words, he is instructed by deeds. And He said sharply reproving him, and showing that his fall was more grievous than the rest, and needed more help. For the matters of blame were two; both that he gainsaid; and, that he set himself before the other; or rather a third too, namely, that he attributed all to himself. To cure these things then, He suffered the fall to take place, and for this cause also leaves the others, and addresses Himself earnestly to him. For, "Simon," saith He, "Simon, behold Satan hath desired to have you that he may sift you as wheat;" that is, that he may trouble, confound, tempt you; but "I have prayed for thee, that thy faith fail not." And why, if Satan desired all, did He not say concerning all, I have prayed for you? Is it not quite plain that it is this, which I have mentioned before, that it is as reproving him, and showing that his fall was more grievous than the rest, that He directs His words to him? And wherefore said He not, But I did not suffer it, rather than, "I have prayed?" He speaks from this time lowly things, on His way to His passion, that He may show His humanity. For He that has built His church upon Peter's confession, and has so fortified it, that ten thousand dangers and deaths are not to prevail over it; He that hath given him the keys of Heaven, and hath put him in possession of so much authority, and in no manner needed a prayer for these ends (for neither did He say, I have prayed, but with His own authority, "I will build my church, and I will give thee the keys of Heaven"), how should He need to pray, that He might brace up the shaken soul of a single man? Wherefore then did He speak in this way? For the cause which I mentioned, and because of their weakness, for they had not as yet the becoming view of Him. How then was it that He denied? he said not, that thou mayest not deny, but that thy faith fail not, that thou perish not utterly. For this came from His care. For indeed fear had driven out all else, for it was beyond measure, and it became beyond measure, since God had to an exceeding degree deprived him of His help, and He did exceedingly deprive him thereof, because there was to an exceeding degree in him the passion of self-will and contradiction. In order then that He might pluck it up by the roots, therefore He suffered the terror to overtake him. For in proof that this passion was grievous in him, he was not content with his former words, gainsaying both prophet and Christ, but also after these things when Christ had said unto him, "Verily I say unto thee, that this night, before the cock crow, thou shalt deny me thri

What the One affirms by His power of foreknowledge, the other denies through love; whence we may take a practical lesson, that in proportion as we are confident of the warmth of our faith, we should be in fear of the weakness of our flesh. Peter seems culpable, first, because he contradicted the Lord's words; secondly, because he set himself before the rest; and thirdly, because he attributed every thing to himself as though he had power to persevere strenuously. His fall then was permitted to heal this in him; not that he was driven to deny, but left to himself, and so convinced of the frailty of his human nature.
